This is sad and atrocious. Not only a Ford Puma (an econobox compared to a Tesla) can read almost all speed limit signs correctly, it can pull speed limit data correctly from its onboard maps when there are no signs. These maps can be updated via WiFi or an on board modem too.

Tesla mocked "big auto industry", but that elephant proved that it can run if it needs to.
